You don't even need a "clean up crew". If that's why you ware wanting snails and crabs, you can skip them entirely with no Ill effects.

Yeah I know.

I mean the tank is a month old and I have no signs of any algae whatsoever...

Obviously I'd like to not have a CUC but I'm planning just in case.

If there is no algae, then you don't have enough food to keep some of these creatures anyway. Just feed reasonably and keep good husbandry/water changes and you'll be fine.

Yeah there's no algae at the mo.. But you hear of many nano tanks that just get annihilated by a sudden algae bloom.

I'll definitely do my best to keep it nice and clean.

They look cute and wave their claws at you lol. At least mine does haha. He eats algae as well, always seems to be eating.

I think they are pretty cool, but not a algae cure IMO. Never had a problem with them eating polyps, but they are among a few crabs that are even this trustworthy. I like a small CUC but it isn't a cure for much except to dislodge food particles and some algaes that hang up in the rock work, but they digest this and poop it out anyway, so your filter is removing the excess food and algae nutrients regardless. Your just running it thru a crab first. There is a old joke there somewhere...

Mine just hangs at the base of my cats paw coral and doesn't seem to be feasting just hanging
